#UTM CONVERTER HOW TO#
#UTM CONVERTER TRIAL#

So If you do spatial analysis using R, you would need to set your coordinate into easting and northing system.

#UTM CONVERTER TRIAL#

But after several trial and errors, it's really not that hard. I am kind of (forced) to do the spatial analysis in R :-).

This bit is part of my work in modeling the hydrology of Cikapundung Catchment.
